(c1. sli-4o) 3 Claims.

This invention relates to safety razors, and more particularly to an improved safety razor of the magazine type.

A main object of the invention is to vprovide a novel and improved safety razor adapted to contain a large supply of razor blades and arranged so that a new razor blade may be moved into position for shaving by a simple manual operation, said operation at the same time causing the old blade to be moved into a storage space in the razor, whereby it is unnecessary to remove the old blade until all of `the blades supplied in the razor are used up.

A further object of the invention is to provide an improved safety razor of the magazine type which is simple in construction, which is very easy to manipulate, which involves only a few parts, and which is sturdy in construction,

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure 13 is a fragmentary enlarged perspec` tive view of one end portion of the flexible band member employediin the form of the invention illustratedlin Figures ll and l2.

Referring to the drawings,'the razor is desgnated generally at I`I and comprises a substantially rectangular body I2 formed with the head I3, said head being provided on opposite sides thereof with the guard flanges I4, I4 arranged to underlie the respective cutting edges of a razor blade I5 disposed in the head in the manner shown in Figure l. The body I2 is formed with a transverse cavity I6 which is generally rectangular in cross-section and which is shaped to receive a supply of conventional safety razor" blades I1 in vstacked relationship, as shown in Figure 4. Designated at IB and I9 are a pair'of parallel, rectangular plate members which are slidably `positioned in the cavity I6 and which are urged apart by a plurality of coil springs 20` secured to and connecting the opposed inside surfaces of the plate members I8 and I9, as shownin Figure 4.

The body I2 is formed with a continuous flat passage 2I which extends around the periphery of the body'and which passes through the head I3. The sides of the passage in the head I3 are open and extend over the guard flanges I4, I4, whereby a razor blade in the passage will be positioned in the manner shown in Figure 1 with the sharpened side edges of the blade exposed on opposite Asides of the passage and overlyingthe guard anges I4, I4. Designated at 22, 22 are spaced lug elements carried on resilient arms 23, 23 secured at their ends to the wall 24 forming the lower portion of the head I3, said lugs 22,' 22 projecting upwardly through openings provided in wall 24 and being spaced apart so as to engage in the locking recesses 25, 25 of a conventional razor blade I5, as shown in Figure 3.

Slidably disposed in the passage 2| is Aa thin, hat, exible ban-d 21 which extends around the periphery of the body I2 in the passage 2| and which is of such a length that the space between its ends is just sufficient to receive a conventional razor blade. As shown in Figure 4, the razor blade I5 is of a length substantially equal to the distance between the ends of the band 21. The passage 2I `is open to the ends of the cavity I6, whereby the springs 20 urge the blades I1 against the band 21, when the band is arranged as shown in Figure 4.

The lower half of the body I2, as viewed in Figure 4, is formed with the :peripheral slot 28 which opens into the passage 2I and which extends from approximately the mid-point of the left end of cavity l to approximately the midpoint of the right end of the cavity I6, as viewed in Figure 4. Designated at 29 is a pin member Secured to the band 2 and provided with a head 3B. The pin member 29 extends through the slot 28 to the exterior of the body l2, the head 3i! being located adjacent to the outer surface of the body at slot 28. It will be readily .apparent that the band 21' may be moved in the'passage 2i by moving the head 3G along the slot 28.

Referring now to Figure 8, it will be seen that the inside 'surface of the left side wall of the body l 2 is formed adjacent the ends of the slot 28 withV the spaced, inwardly projecting lug elements 3L,

3l which are symmetrically located on; opposite` sides of the slot 28 and which are spa-ced apart sufficiently to receive the band 2'! between them.

The lugs 3l, 3| serve as guide means for the band 21 and :also serve to defiect a used razor bladeinwfardly .into the cavity I6 when the band 2T is moved -in a counterclockwise direction, as viewed in Figure 5, whereby a` used razor blade may be guided into'the left end of the cavity I5 for storage therein.

As shown in Figure 4, the band 21 is approximately equal in thickness to the thickness of a conventional razor blade l5, whereby the band 21 may readily urge a blade through the passage 2| when the band is moved by means ofV the -pin 29;

Assuming that a blade i5 is in the position shown in Figure 4 and it is--desired to substitute a new blade, the head 3l! is rst moved in a counterclockwise direction, as viewed in Figure 4, whereby the right end of the bandl 2'! engages the used blade l5 and forces said used blade into the Iposition shown in- Figure 5, whereby the used blade is deected inwardly into the left end of the cavity I 5. When the head 3G is moved so that the pin 29 engages the right end of slot 28;

as viewed inV Figure', the' used blade will havebeen moved completely into'the cavity i6. The head 30 -is then moved clockwise to the position shown in Figure 6, wherein the pin 29- engages the left end of slot 28 and the ends of band 21' are dis-posed adjacent opposite ends oi'- the new blade at the right endy of the stack of blades I?, as shown in Figure 6. The head Seis then moved to the position sh-own in Figure 4, whereby the band 2'! moves the new blade in a counterclockwise direction, as viewed in Figure 6, until the blade moves into the head I3 and becomes interlocked withv the lugs 22, 22. The razor is now ready for use.

The razor is initially furnished with a stack lof blades Il which substantially fills the' cavity l5. As the razor is used, the used blades accumulate in the left end of the cavity I6', new blades being constantly `furnished from the stack l1. After al1 of the new blades are used, the blades will all be contained in the vcavity I6 to the left 4of the plate member I9, as viewed in' Figure 4, whereupon it is necessary to remove the used lblades and replenish the supply of blades. The body l2 is provided with theA removable frontV and rear cover plates 32, providing access to the interior of cavity I6v by the'removal of either of said cover plates.

As shown' in Fig-ure 4, suitable friction springs 33, 33 may be provided in the head I3, said springs having free end portions which engage the band 21 through suitable openings'formed in the inner wall of passageZ I.

In the form of thefinvention" illustrated inFig-' ures 11, 12 and 13, the fiexible band, designated at 27', is somewhat thicker than ra razor blade and is slidably retained in a groove or channel, shown at 34 in Figure 12, whereby the band 21 is maintained centered at all times. The ends of the band 21 are formed with centered lugs 35 engageable in notches 3S in the ends of the razor blade l', as shown in Figure 1l, whereby the blade I5 is also maintained centered.

While specific embodimentsV of an improved safety razor of the magazine type have been disclosed in the foregoing description, it will be understood that various modifications within the spiritof the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as deined'by the scope of the appended claims.

What is claimed is:
